What happened

Record-breaking photonics approach traps light on a chip for millions of cycles Gaby Clark scientific editor Robert Egan associate editor For years, scientists have dreamed of using atomically thin van der Waals (vdW) materials to build faster, more efficient…

Why it matters

These materials can be stacked and tuned with extraordinary precision, opening possibilities far beyond those of conventional technologies.

Common ground

The challenge is that they are extremely fragile, making them notoriously difficult to shape with standard nanofabrication tools.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
